Oh, dear god. Why would you choose the worst of the worst examples? Here is how they look when they are not homemade, and actual time and care is put into them: http://i.imgur.com/9mZB0.jpg .......... http://fc08.deviantart.net/fs71/f/2012/105/a/0/tartii_fursuit_by_tartii-d4wadrb.jpg .......... http://img.ponibooru.org/_images/6a0798de09c998f412e2fbb4d4de06fe/30123%20-%20applejack%20cosplay%20furry%20fursuit%20rainbow_dash.jpg ........ http://fc07.deviantart.net/fs71/i/2010/199/4/8/Lombax_Fursuit_by_Stathgar.jpg

Those are just a few examples. They just like to cosplay, like any other fandom. And when you have no money to pay someone else to make them... well you get atrocities like the ones you posted. But if done right, furries can be pretty darn cool.
